IMPROVEMEN IN APPARATUS FOR RENDERING LARDI TREATING OFFAL, 86 2.

Specification forming part of Letters Patent No. 136,208, dated February25, 1873.

To all whom it may concern:

Be it known that I, JOSEPH N. B. BOND, of

the city, county, and State of New York, have invented a new andImproved Process and Apparatus for Deodorizing the Gases fromLard-Boiling and other Establishments; and I do hereby declare thefollowing to be a full, clear, and exact description thereof which willenable those skilled'in' the art to make and use the same, referencebeing had to the accompanying drawing forming part of thisspecification, which drawing represents longitudinal vertical section ofmy apparatus.

This invention consists in a decomposingehamber filled with ironturnings or other suitable material, and situated in the interior of afurnace, said chamber being connected at one end with a pipe whichcarries ofi' the gases from a lard-boiling or other establishment of asimilar nature, while the other end ofthe decomposing-chamber connectsby a suitable pipe with a condenser. In this pipe extends asteam-nozzle, whereby the passage of the gases through thedecomposing-chamber and into the condenser is accelerated. The

. condenser is supplied with water under pressure which is injectedthrough a rose-head, and it also connects with a steam-pipe, whichserves to blow out the sediment accumulating in said condenser. Theinvention further consists in the process of deodorizing gas fromrendering-tanks; namely, by passing the gas, in connection with. steam,through a highlyheated chamber, containing iron filings or othersuitable materials, as specified hereinafter.

In the drawing, the letter A designates a chamber made of cast-iron orother suitable refractory material, and situated in the interior of asteam-boiler furnace, B, so that it is exposed to direct action of thefire, and that the temperature of the chamber is raised to a highdegree. Said chamber is filled with iron turnin gs or other suitablematerial, according to the nature of the gases to be treated, and itconnects at one end with a pipe, 0, which serves to carry off the gasesfrom a lard-boilin g or other establishment of a similar nature.From-the opposite end of said chamber extends a pipe, D, which leadsinto a condenser, E, said pipe being connected to a head, F, providedwith a series of nozzles, G, which dip beneath the water contained inthecondenser.

Through the side of the pipe D extends e pipe, H, which forms a nozzle,to, in the interior of said pipe, and which connects by a pipe, J, withthe steam-boiler K, so that by injecting steam into the pipe D thepassage of the gas through the decomposing-chamber 7 A is accelerated.The pipe I connects with a reservoir containing water under pressure,and from the pipe J extends a branch-pipe L down into thedecomposing-chamber.

The contents of the condenser are blown off through a tail-pipe, M.

When the chamber A is heated, the gaspipe 0 is opened, and as the gascomes in contact with the heated iron turnin gs or other materialcontained in said chamber, it (the gas) is decomposed, and a largepercentage of its offensive odor is destroyed. The gases escaping fromthe decomposing-chamber pass through the pipe D into the condenser,which is supplied with cold water through pipe I, and thereby a largepercentage of the gases is condensed. The non-condensable gases arecarried through a pipe, N, beneath the grate in the furnace B, where thesame are consumed. The sediment which accumulates in the condenser isblown off from time to time by injecting steam into it through the pipesJ and I, the connection of the pipe I with the reservoir being closedfor the time being.

By this arrangement the offensive gases generally escaping fromlard-boiling or other establishments of a similar nature can beeffectually destroyed, and such establishments can be worked withoutdetriment to the neighborhood.

What I claim as new, and desire to secure by Letters Patent, isi 1. Thecombination of a decomposing-chamber, A, and condensers E, with agas-coir ductor, O, pipe D, and steam generator, K, substantially as andfor the purpose shown and described.

2. The process for deodorizing gas from rendering-tanks, viz., passingthe gas, in connec tion with steam, through a highly-heated chambercontaining iron filings or their equivalent, substantially as described.
